SPECIFICATION forming part of Letters Patent No. 635,617, dated October24, 1899.

Application iiled January 4, 1899. Serial No. 701,145.l (No model.)

To all whom it may concern:

Be it known that l, GEORGE WV. TUCKER, a citizen of the United States,residing at Gridley, in the county gf Coffey and State of Kansas, haveinvented certain new and useful Improvements in Cultivator Attachments;`

and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to'cultivator attachments; and the purpose of thesame is to cut out weeds and also pulverize the soil, being applicableto any cultivator now in use and adjustable to any depth.

The invention consists of the construction and arrangement of partshereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of theimproved attachment, showing part of a beam in connection therewith.Fig. 2 is a longitudinal vertical section of the same. Fig. 3 is a frontelevation. Fig. 4 is a rear elevation.

Referring to the drawings, wherein similar numerals are ,utilized toindicate corresponding parts in the several views, the numeral ldesignates a shovel, which is arranged in horizontal position, orapproximately so, and in accordance with the adjustment of the same andhas opposite cutting edges 2, converging from the rear to a front point3. The opposite portions of the body of the shovel, as at 4, riseregularly in curved lines above the level of the cutting edges 2 andtoward the central line of the shovel for the purpose of casting orthrowing off the soil or Weeds that may come up thereover. To the rearcentral portion of the shovel a shank 5 is secured and extends therefromin an upward oblique line and through a slot 6 in the rear upper portionof the said shovel. The greater portion of the rear part of the shank 5is cylindrical, as at 7 and is provided with a bored circumferentialflange 8. The said rear part of the shank is removably fitted in asubstantially U-shaped clamp 9, which has the upper arms 10 thereofembracing the lower end 5o of a post 11 and adapted to be held in fixedposition by a transversely-extending clampbolt 12. The arms 10 of theclamp 9 areprovided With inwardly-extending shoulders 13 above theopening, through which the shank passes to serve as a limiting means orstop for the inward extent of the post 11 into said clamp and withoutinterfering with the dimension of the opening for the reception of theshank.

The lower end of the post 11 has a rearwardly-extending arm 14, which ishorizontally disposed and has a terminating vertical screw-bearing l5,inwhich is mounted a screwbolt 16. The upper portion of the post 11 isbifurcated, as at 17, and the arms 1S, formed by the bifurcation, haveslots 19 therein. Withinthe upper bifurcated end of the post 1l thelower end of a cultivator-beam 20 is removably secured by a lower bolt21 and au upper break pin or bolt 22, which is fitted in the slots 19.

To cover the rear open or slotted part 6 of the shovel 1 and to protectthe clamp 9, a shield 23 is mounted on the top central portion of saidshovel and is of such form as to regularly continue the lines of thebody thereof in an upward direction. The upper central portion of thesaid shield 23 has opposite ears 24, which are removably secured to thepost 11, below the bifurcation 17 thereof, and the purpose of saidshield is to prevent the collection of cut weeds or debris at the rearof the attachment and over the clamp, as well as to avoid clogging ofthe earth at such points and thereby always keep the clamp free and incondition for operation. The addition of this shield facilitates thegeneral operation of the shovel, and it can be quickly removed at anytime to operate the clamp, or the bolt 12, controlling the latter, maybe reached, as shown by Fig. l, without detaching said shield.

When cultivating level ground or an approximately level surface, theshovel occupies a horizontal position, with the shield 23 restingsquarely thereon along its longitudinal edges. Should it be required tovary the pitch of the shovel to cause it to run shallow or deep, theclamp-bolt 12 is loosened, and upon turning the set-screw 16 to theright the rear end of the shank 5 will be depressed and cause aproportionate rising of the point of the shovel, due to the tilting ofthe shovel and clamp upon the bolt 12 as a fulcrum.

IOO

On the other hand, a backing of the set-screw ll will permit the pointof the shovel to lower and the rear end of the shank 5 to rise, thisresulting from having the major part of the shovel in advance of thepivot clampscrew 12. After the shovel has been adjusted to the requiredpitch its position is fixed by retightening the pivot clamp-screw l2.Should the ground be rolling or slope slightly, the shovel can beadjusted to conform to the surface by loosening the clamp-screw l2 andturning the shovel upon the shank 5 as a journal within the clamp 9.This angular adjustment brings the shovel parallel with the surface tobe treated, and a retightening of the clamp-bolt secures the shovel whenadjusted. In slight angulaiadjustments of the shovel the shield 23 mayremain in posit-ion, because the slight space formed between the lowside of the shovel and the adjacent edge of the shield will present noobstacle to the successful operation of the shovel. V'Vhen the angularadj ustment is great, as for side-hill cultivation, the shield must beomitted or replaced by one of special adaptation. By such adjustmentalso the depth of penetration may be regulated and the Work of theshovel positively governed for surface treatment of the soil orpulverizing purposes.

The proportions and dimensions of the several parts may be varied, aswell as the minor details of construction, without in the leastdeparting from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is- 1. In acultivator attachment, the combination of a post adapted to be securedto a beam and having a rearwardly projecting arm, a clamp adjustablyconnected to the lower portion of said post, a shovel having a shankremovably and rotatablyengagin g said clamp, and a setbolt in the saidarm adapted to engage the shank.

2. In a cultivator attachment, the combination of a post or supportadapted to be attached to a plow-beam, and a shovel or analogous deviceadjustably held by the lower end of said post or support and mounted toturn upon a central longitudinal axis to adapt the side portions of theshovel to the surface condition of the soil, substantially as described.

3. In a cultivator attachment, the combination of a post or support, anda shovel or analogous device adj ustably connected to the lower portionof said post or support and mounted to turn upon a transverse and acentral longitudinal axis whereby the side portions of the shovel can beadapted to the surface condition of the soil and the point elevated orlowered, substantially as described.

4t. In a cultivator attachment, the combination of a post adapted to besecured to a beam and having a rearwardly-projecting arm, a clampadjustably connected to the lower portion of said post, a shovel havinga shank removablyand rotatably engaging said clamp, a set-bolt in thesaid arm adapted to engage the shank, and a shield for removableapplication to the post and shovel, substantially as specified.

5. In a cultivator attachment, the combi; nation of a post or supportadapted to be attached to a plow-beam, a shovel or analogous deviceadjustably held by the lower end of said post or support and mounted toturn upon a transverse and a longitudinal axis, means for securing theshovel in an adjusted position, and an adjustable and detachable shieldon the top of the shovel, substantially as and for the purpose setforth.

In testimony whereof I afiix my signature in presence of two witnesses.

GEORGE W. TUCKER.
